The drag machine is' rolled overand the car moved to the left, thus putting the cope under the cope machine133, and the receiving tableor mechanism 44 under the drag. With the car at rest in that position the dragis lowered onto the flask receiving means 41-and the pattern is drawn by the machine 34. The

cope is raised by the machine 33 and the cope pattern drawn! The car is then trav- Zersed toward-the; right bringing the drag from which the pattern has beendrawn by chine 39, and the cope is lowered onto the dra so that the complete mold may be lifted n will be obvious to those skilled in the the appended claims' y Iclaim: V
